Article 5

If, as a condition of protecting the producers of phonograms, a Contracting State, under its domestic law, requires compliance with formalities, these shall be considered as fulfilled if all the authorized duplicates of the phonogram distributed to the public or their containers bear a notice consisting of the symbol, accompanied by the year date of the first publication, placed in such manner as to give reasonable notice of claim of protection; and, if the duplicates or their containers do not identify the producer, his successor in title or the exclusive licensee (by carrying his name, trademark or other appropriate designation), the notice shall also include the name of the producer, his successor in title or the exclusive licensee.
